position, whereby it can be moved away from` the doorway, the object of the invention being to provide an improved organization of lnechanism by means of whicll a door flush with the door-casing can be shifted into po-` sition with facility and with comparatively littlelabor to permit it to be moved away from,v the doorway, the present lnechanism being an y improvement in part over that shown and de-1 scribed in my contemporaneously-pending application, Serial No. 29,879, filed September,

A further object of the invention is to provide an improved Organization of mechanism for supporting and controlling the movement of the door, comprising rock-shaft mechanism for supporting the door on the car-body and a rockeshaft actuator for shifting said door. y

Another object of the invention is to' pro-- vide improved means for maintaining the; door part way Open, thereby to permit thevl ventilation of the car.

Another object of the invention is toY provide, in connection with supporting means for the door, a rock-shaft actuator connected therewith by means having pivotal conuec tion with such actuator, whereby the door;

nlay be swung outwardly from its bottom.

In the drawings accompanying and forming part of this specification, Figure 1 is a view.

of a part of a car-body, showing this improved organization 0f door shifting mechanism and Fig. 2 is an enlarged view of one part of;

such mechanism.

Similar characters of reference designate corresponding parts in the different figures of the drawings. Y

In the form thereof herein shown and described and which may be its preferred form,- ,ifdesired, a track 2 is secured to the oar`y body 3 above the door, and O11 tllis track is located hangermechanism, comprising in the present instance a plurality of hangers 4, which may in practice be provided with rolls 5 engaging said track, the hangers being usually so constructed as to prevent play thereof on the track. Thesehangers,which are shown located relatively remote to each other, are connected with the door by suitable means designated herein as rock-shaft lnechanism 6, for which purpose the door is provided with a pair of plates 7, having ears 8. This rock-shaft mechanism in the form shown comprises a rock-shaft 6, having a pair of arms G and 12, the arm 6" heilig bolted or pivotally secured to one of the door-plates 7, while the arm 12 is connected with a'crank 6', having a horizontal journal 9, projecting into one of the hangers 4, it being secured therein in solne suitable manner, the lower end of said crank being pivotally secured to the other door-plate 7. ln practice this rock-shaft mechanism might be formed as an integral structure; but in the present instance the arm 12 of the rock-shaft is bolted to the crank 6 in such manner that such parts may be operated at the same time, and for all practicable purposes the crank 6' and arm 12 might be considered to constitute one arm of the rock-shaft. For actuating this rock-shaft mechanism to throw the door outwardly and upwardly a lsuitable actuator is provided, shown herein as a lrock-shaft 13, projecting toward the top and bottom of the door and shown located adjacent to one side thereof with its axis located substantially parallel with the plane of vthe door, suitable keepers 14 being located `on the door for the lower end of this rockshaft. This rock-shaft actuator is connected with the rock-shaft mechanism by suitable connecting means, Which in the present instance comprises a bell-crank 15, pivotally secured to one of the hangers 4, one arm 15 thereof being shown connected with the crank 6 and arm 12 of the rock-shaft mechanism by means of a link 16, through which a bolt connecting the two parts together projects, while Athe other arm 15 of this bellcrank is connected with the rock-shaft 13 by a link 17 and a crank 1S, the link being secured to the bell-crank and to one part of such crank and the crank being shown IOO mounted in a suitable bearing 19, carried by one of the hangers-for instance, that hanger which carries the bell-crank--the lower end of said crank 18 being pivotally secured to the rock-shaft 13. By means of this pivotal connection the bottom of the door may be swung outward after it is released from the brackets 25, so that such door may be freed from any freight which may have fallen against it. v As the door is shiftable upwardly and outwardly such upward movementtends to carry the freight away from the car-door and to shift it suflciently to enable the door to be swung outward at its bottom and permit such freight to be moved away from the door without the necessity of cutting through such door, as has been frequently necessary.

For shifting the rock-shaft 13 suitable means is provided, shown herein as a bar 20, by means of which the shaft is rocked. This bar is shown provided with an eye 21 at its end for the reception of projections-one, as 22, secured to the door, and the other, as 23, to the car-body-whereby when the arm is in engagement with either one of the projections the rock-shaft will be held against movement. In the present instance it will be noted that the projection 23 is located nearer the doorway than is the projection 22. The length of the bar 20 is such that in order to have the projection 23 coperate therewith it is necessary that the door be moved laterally on its track a certain distance, whereupon on swinging the bar 20 into position to engage the projection 23 the door will be maintained in this partially open position and so permit the ventilation of the car. Of course it will be understood that the projection 23 may be located at any desired distance from the doorway, according to the length of the bar 20, or a numberof such projections may be provided to permit the door to be opened various distances, if desired.

The door is provided with a handle24, by means of which the bottom may be pulled out after such door is shifted upwardly and outwardly, and suitable devices 25 are provided at the corners of the doorway to guide the same in its movement.

In use on the operation of the rock-shaft actuator 13 the crank 18 will beoperated to shift the bell-crank 15, thereby to operate the rockshaft mechanism 6, connecting the hangers 4 with the door, and so throw the door upwardly and outwardlyinto position whereby it can be shifted laterally away from the doorway, to either side of which it may be moved. A suitable stop 30 is, however, provided in the present instance for the door to st-rike against when shifted on its track into position to close the doorway.

In the organization shown and described in my contemporaneously-pending application hereinbefore referred to the mechanism is somewhat different, and in order to shift the doorupwardly and outwardly duplicate crank mechanisms connecting the door with the body of the car and duplicate bell-cranks and connectors are shown. In the present instance, however, this duplication of parts is by a simple organization of mechanism rendered unnecessary, the organization being such that the door is connected with the carbody by practically one mechanism and designated herein as rock-shaft mechanism, which is connected with the rock-shaft l0- cated at one side of the door by a single bellcrank, whereby the mechanism is very much simplified. This bell-crank is shown so located on the hanger that its direction of movement is parallel to the plane of the door, and by locating it on the hanger adjacent to and at the outer side of the track it is in position vto assist in forcing the lower part of thc hanger inward and the upper part thereof outward against the track when the actuator is shifted, since part of the weight of the door is carried bythe bell-crank when said actuator is shifted, the organization being such that the door is eccentrically supported on the track at this time, so that the friction of the hanger on the track will be Stich that the door will be kept from moving to freely when the car is bumped. Further-- more, it will be seen that practically all of the mechanism is located free of the door, it being carried in the present instance above the door, so that the door is free of the weight thereof, which thus renders the door more easily shifted.

In conclusion I desire to state that this improvement may bc used in al1 kinds of freight and box cars-such as ref rigerator-cars,&c. and can also be used in connection with structures other than freight-cars, if desired, so that the term car-body as used herein and in the claims is not to be construed as a limitation to structures of that class.
